Specification of Letters Patent.

Patented April 16, 1907'.

Application filed August 18, 1906. Serial No. 331.166.

1'0 Utl/f wle/om t TV1/ty concern: I

Be it known that I, JOHN R. HUNT, a citi* the county of Glenn and State of California, have invented certain new and provements in Wrenches, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in ratchet-wrenches, and consists in the novel the inner end of the shank upon a transverse pivotpin ll, so that it has a swinging movef Zen of the United States, residing at Floyd, in

nient independent of the shank suiiicient to permit the pawl to be engaged with and disuseful linengaged from the ratchet-teeth 5. The lat ter are formed at one end of the rotary head 2, which Ahas around its center an annular groove or channel 12, adapted to receive the enlarged outer end of the shank, the two sections of the latter at said end being formed' construction, combination, and arrangement l with semicircular bearing portions 13 to enof parts hereinafter described and claimed.

The object of the invention is to provide a wrench of this character composed of a few simple parts which may be made and asseinbled at a comparatively small cost to produce a strong, durable, and efficient tool.

Further objects and advantages of the invention, as well as the structural features by means of 'which they are attained, -will be made cleai by an examination of the specification, taken in connection with the accome panying drawings, in which the same reference-numerals indicate corresponding .portions throughout, and in which*d l Figure l is a perspective view of the improved ratchet-wrench. Fig. 2 is a longitu-v dinal section through the same. Fig. 3 is a top plan view of the wrench, showing it applied to a nut, bolt, or the like 5 and Fig. 4 is a detail longitudinal sectional View through one end of the wrench, the plane of the section being at iight angles to that of Fiv. 2.

The improved wrench comprises a body or vshank l, a rotary head 2, mounted in one end of the shank and p'rov'ded with sockets to engage nuts or bolt-heads, and a handle 3, end lof the shank and carrying a pawl 4, which engages an annular series of ratchet-teeth 5, formed upon the head 2. The shank tapers from its outer to its inner end and is composed of upper and lower sections 6 7, united by a rivet or the like 8, as shown in Fig. 2.

The upper section 6 is formed in its top with a channel or groove 9, which extends longitudinally from its small inner end to its enlarged outer e'nd, where it opens into a transversely-extending recess or portion l0, formed at the enlarged ends of bothl of said sections. The channel 9 is adapted to receive the pawl or dog 4, which inner end.

The handle is pivoted, as seen in Fig. 2,

cut-away Y,

l tudinal is formed integral with the handle 3 at its 1 Both ends of the rotary head project beyond the outer side faces of the shank, and in them are formed sockets 14 of the size and shape of the nuts, bolteheads, or the like upon which the wrench is to be used.

In operation one of the sockets 14 is'engaged with the nut or the head of the bolt to be turned, as shown in Figs. 3 and 4 of the drawings, and the handle 3 is then .grasped and turned in a direction that will cause the pawl 4 to engage one of the ratchettceth 5, and thereby cause the head 2 and the nut or bolt to turn with the handle and its shank. When the handle is swung in the opposite direction, it turns upon its pivot il to disengage the pawl from the ratchet, thus ene abling the pawl to take a fresh grip upon the ratchet and enabling the nut or bolt to be continuously turned without removing the wrench from it.

.Having thus described my said invention, what l claim as new, and desire to secure by Letters Patent of the United States, is-

1. A wrench comprising a shank formed l in the aperture in said end and formed at one end with an annular series of ratchet-teeth disposed in said recess in the shank, said head having in its opposite projecting ends sockets to receive a nut or bolt-head, and a handle pivoted in said groove at the outer end of the shank and formed with a pawl to work in said groove and engageA said ratchet-teeth.

2. A wrench comprising a tapering shank composed of upper and lower sections each having its larger end recessed upon one side and formed with a bearing-aperture, the upper section being also formed with a longigroove, a rotary head having at its center an annular groove to receive the apertured ends of said shank-sections and in its in projecting sockets to enga ge a nut or the like,

TOO

IOS

yinner end of the shank and formed With an integral pawl to enter said groove in the shank and engage said ratchet-teeth.

1n testimony whereof I hereunto aHiX my signature in presence of' tWo Witnesses.

JOHN R. HUNT.
